I wrote a post about the differences between the Acer XF240H and the KG240 found here. I ended up keeping the XF240H because I felt that it was the better monitor based on build quality and stand adjustability. The colors on both displays will need to be adjusted as with most monitors out of the box as they are awful. The settings I ended up using should work on both the Acer XF240H and the KG240 as I believe they are both the same panel.
